    :alt: Build status

pgmp is a PostgreSQL extension module to add support for the arbitrary

precision data types offered by the GMP library into the database.

The extension adds the types mpz_ (arbitrary size integers) and mpq_

(arbitrary precision rationals) to PostgreSQL and exposes to the

database all the functions available in the GMP library for these types,

providing:

- higher performance arithmetic on integers respect to the ``decimal``

  data type, using numbers only limited by the 1GB varlena maximum size;

- a rational data type for absolute precision storage and arithmetic;

- the use of specialized functions to deal with prime numbers, random

  numbers, factorization directly into the database.

The GMP data types can be stored into the database, used in mixed

arithmetic with other PostgreSQL numeric types and indexed using the

btree or hash methods.

Please refer to the documentation for installation and usage, either

online__ or in the ``docs/`` directory.
